Navigate a maze made of mirrors and discover the law of reflection. Every light ray bounces at exactly the angle it arrived — use this to guide beams through the labyrinth.
The law of reflection: angle of incidence equals angle of reflection. Multiple mirrors create complex beam paths. Parallel mirrors create infinite recursive reflections — each image slightly dimmer than the last.
Click and drag mirrors to reposition and rotate them. Trace the light beam's path through the maze. Try to hit all target points using the fewest mirror moves.
The James Webb Space Telescope uses 18 hexagonal mirrors working together with nanometre precision to focus light from 13 billion light-years away — the same law of reflection, at cosmic scale.
